Patented May 27, 1930 l FREDERICK M.: vENzImjoI rIIILADELrH-Ia, PENNSYLVANIA f BUILDING CONSTRUCTION "Irhis invention, generally stated,"A relates to a building construction 'and-"has more especial relation to av fioor construction.` f

'One of the greatdisadvantages in'concrete and likefioorings isth'at" frames or-sup'ports o f Wood are employed to accept the "concrete,

which woodgreatly depreciates inf value as it is'used from time to time.'

The leading object ofthepresent invention.

-10 is `t'oprovide a temporaryflooring construction composed'entirely of metal.y v f A further object of the present Ainvention is to provide a novel forml of metallic support for the concrete Which is chiefly made of sheet Afurther object ofthe present invention resides inthe `provision of general 'details of constructionandin the arrangement, combination, and .connection of partsA for attaining 2O the results sought lthe foregoing objects.'

Other andfurther objectsnot at this time appearing will behereinafter referred to.

I yFor the 'purpose of illustrating my invention I" have shown in the accompanying drawings one formA thereof which is at `present preferred by me, since the same has been found in practice to give satisfactory andreliablejresults, although it is to be Vunderstood that the various instrumentalities of which my'v invention consists can bey variously arranged andjo'rganized and that my invention is not limited to the-precise arrangementand f organization of the instrumentalities as here-- in shown anddescribed.
